I've not found a solution to this anywhere. I've got Logic Pro 9 and hooked up a M-Audio Oxygen 49. The computer and software see the Oxygen okay and I can play any sound I want through the software. Until I hit play - trying to add a track to a recorded song - and the led indicator makes some strange outputs and goes black and freezes. The only way to get it back on is to restart LP. Anyone else have this problem or know what could be causing it? Thanks.

    I too have an oxygen 49 with Logic Pro and it is working well. Did you check to make sure you are using preset 10? This is the preset recommended for use with Logic Pro. Your led status acting strange is an indicator that midi data is flowing back to your keyboard and causing it to freeze. I believe on the keyboard, turning it off and on while pressing the two selection keys resets the keyboard. This info is in the online manual from m-audio. However, make sure you are on the correct preset.

    First.. make sure none of the tracks are sending their MIDI output to the Oxygen, it creates no sounds

     

    Second...  there's a possibility is Logic sees the Oxygen 49 as a generic "control surface" or has assigned an incorrect control surface.

     

    Another possibility is that Logic has a corrupted "control surface" preference file.

     

    A test... go to the upper left MENU in Logic, select Preferences/Control Surfaces/Bypass All Control Surfaces

     

    Quit Logic, turn the Oxygen Off ot unplug the USB cable, restart the Mac, let it settle a minute, power on the Oxygen, wait 30 seconds and then start Logic. If the Oxygen seems to be working ok then it's control surface related.

    How do I check if the tracks are sending MIDI to the Oxygen? I'm pretty sure that's what's going on but don't know how to stop it. Thanks much.

     

    Have you first tried the test I suggested.

     

    --------------------------------------------

    A test... go to the upper left MENU in Logic, select Preferences/Control Surfaces/Bypass All Control Surfaces

     

    Quit Logic, turn the Oxygen Off ot unplug the USB cable, restart the Mac, let it settle a minute, power on the Oxygen, wait 30 seconds and then start Logic. If the Oxygen seems to be working ok then it's control surface related.

    Using the Inspector on the right hand side you cab see where the track is sending it's output.  MIDI could only be sent to the Oxygen from an Internal MIDI track or an Environment Object with it's output set to the Oxygen IN.

     

    Sounds like a control surface thing to me.

     

    Go to that menu selection I described above and select  "Rebuild Defaults"

    Then Test

    If No change select "Bypass All Control Surfaces"

    Test

    What model Oxygen is that, what color?

     

    I have an Oxygen61 (blue model) sitting on top of my main keyboard and it works perfectly with both Logic/Mac and a PC.

     

    Did you install any software for the Oxygen?

     

    Try this, quit Logic and go to  Users/YourName/Library/Preferences and delete the    com.apple.logic.pro.cs

    file, it's the only file in that folder that has the .cs extension.

     

    However... if you're running Lion of ML the Library folder is hidden, you can unhide it via a menu command.

     

    Or using Apple's  "GO"  menu item select  "Go To Folder" and type this (or copy/paste)   ~/Library/Preferences

    and you will get there.  Delete the   com.apple.logic.pro.cs   file.

     

    It will be rebuilt next time Logic starts.

    While this may be an M-Audio problem...while you're at it it's probably a good idea to delete Logic's preferences as well.

    Check near the bottom.

    I guess it could be hardware, USB cable, the Keyboard itself.

     

    Did you install any software for the Oxy49 and if you did is it the most recent from the M-Audio site?

    The blue oxygen is class compliant meaning it will work, just by plug and play. There are a couple things you might try.  First turn off you keyboard, then hold down the + and - keys on the oxygen while turning the power back on. This resets the oxygen to the default factory settings.

     

    You also can go to the m audio website and under the earlier OS x's such as snow leopard, there are drivers available. I have done this and it did allow some different functionality, even though I'm running 10.8.2. I do have a question, is the oxygen plugged directly into the computer, and what computer and OS do you have?
